There has been political fallout from a WikiLeaks cable related to the U.S. military base on Diego Garcia in the Indian Ocean. The nation of Mauritius announced plans on Tuesday to contest the legality of a new maritime reserve park around the disputed Chagos Islands after a leaked U.S. cable suggested the park was a ploy to stop uprooted islanders returning home. Britain leased the archipelago’s biggest island, Diego Garcia, to the United States in 1966, paving the way for the construction of a huge airbase which required the forced removal of some 2,000 Chagossians. Publicly, the British portrayed the establishment of the marine park as a move to save the environment. But a U.S. diplomatic cable dated May 2009, disclosed by WikiLeaks, revealed that a British Foreign Office official had privately told the Americans that the decision to set up a marine protected area would "effectively end the islanders’ resettlement claims."
